functional costing

Functional costing is a method used in defense management to analyze the costs associated with achieving specific military objectives. Instead of traditional budgets that list expenditures by department (like navy or air force), functional costing groups costs by objective, such as "maritime defense" or "coastal defense". This approach allows for a clearer understanding of how resources are allocated to achieve particular goals and facilitates more rational decision-making by comparing the costs of different programs that contribute to the same objective. It helps defense planners assess the efficiency of spending and make informed choices about resource allocation, moving beyond simple accountability to a more strategic evaluation of effectiveness.1
